Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to communication intercom technical field, concretely is a tunnel communication intercom device. BACKGROUND
[0002] When the personnel in the tunnel use the intercom in the tunnel to talk, the voice signal is first converted into an electric signal by the microphone built-in the intercom, and then the electric signal is modulated to a specific radio frequency carrier by the transmitter thereof, and is transmitted in the form of radio signal through the antenna. The wireless signal transceiver in the tunnel receives the radio signal, and transmits it to the connected signal amplifier for amplification processing to enhance the signal strength, so as to ensure that the signal can be stably transmitted to the optical fiber transmission machine. The optical fiber transmission machine converts the amplified electric signal into an optical signal, and transmits the optical signal to the relay station through the backbone optical cable. The relay station converts the received optical signal back into an electric signal, and radiates the electric signal through the antenna connected thereto to convert it into a radio signal propagating in the air for the intercom outside the tunnel to receive. After the antenna of the intercom outside the tunnel receives the radio signal, the receiver thereof demodulates the signal to restore the original voice signal, which is played through the loudspeaker, so as to realize the voice communication between the intercoms inside and outside the tunnel. Conversely, the signal transmitted by the intercom outside the tunnel is also transmitted in reverse through the above process to the intercom inside the tunnel to complete the two-way communication.
